书上的是he's having a bath .为什么不是这样he's bathing He's having a bath 请问have已经是动车了,is可以直接去掉吗（he having a bath)为 he is having a bath he has a bath he is having a bath he had a bath When he arrived I was having a bath. When后面不是跟持续的动作吗 he arri ( )He went to bed ____ having a bath.选什么 He felt relaxed after having a hot bath 这里的felt、relaxed是什么词性 请问where he's going?结构为什么是He'不是 is he? 看一下这两句英语的语法：书上是这样的：He was now the king.我想为什么不是He was the kin What a lot of trouble he is causing 这里的 trouble 为什么不是复数 加 S Where is Mr.Read?He is in a r_.He's having dinner with his f he's a pirate
